Abstract

We examine one simple mechanism which leads to approximate maximal ν_μ- ν_τ oscillations in the standard see-saw model. In particular, we show that this scheme could be implemented in the Exact Parity Model (also known as the mirror matter model). Within this framework the solar neutrino problem is solved by maximal ν_e → ν'_e oscillations (with ν'_e is the essentially sterile mirror partner of ν_e) and the LSND evidence for ν_e → ν_μ oscillations can also be explained.
